Re: Orbital Sciences Corporation
OSC has already used their modified L1011 to launch a Pegasus. Last
month they launched a stretch Pegasus from the plane for the first time.
Unfortunately they are using new control software in the Pegasus and it
did not properly take into account the difference in the Phugoid
frequency of the stretched bird. The result was positive feedback in the
yaw control loop causing failure of the main wing. A self destruct
charge was detonated from the control facility aboard the L1011. They
are due to try again sometime soon.
